Daniels and O’Leary are both graduates of the NASCAR Drive for Diversity Pit Crew Development Program, according to NASCAR.com.

They changed tires for the No. 52 Rick Ware Racing team at Sunday’s race, which was won by Denny Hamlin.

\"I try not to put pressure on myself and think about [making history],\" O’Leary, 27, told \"Good Morning America\" Monday. \"With that being said, I never ever would have expected the impact I could have on females behind me, younger girls.\"

\"I think that in itself is the most rewarding thing of this whole process,\" she added. \"Parents tell me they’re so excited they can show their daughters, and fans will see me working and say, ‘Oh my gosh. This is awesome, keep it up. I love seeing women out there.’\"

It’s RACE DAY!! Super excited to be pitting my very first #Daytona500 race today @DISupdates! Catch me on the 52 car for @RickWareRacing changing the fronts @ 2:30pm ET on @FS1!?????? #MakingHistory

Daniels called her history-making moment with O'Leary a \"dream come true.\"

\"All the women out there, we can really do anything we put our minds to no matter what anybody else has to say,\" she told ESPNW. \"As long as you believe in yourself, you can do anything.\"
